CNTT-v0.3

Version 0.3 of the CNTT package.

New features:

• DFT capabilities (outsourced to Quantum Espresso);
• Fourier interpolation of k-points;
• minor bug fixes.

CNTT-v0.2

Version 0.2 of the CNTT package (old swcnt-bands package).

New features:

• package has been renamed to CNTT;
• new logo;
• new plotting features: labels, simultaneous multiple plots and comparison;
• improved plot of the kpoint valley minima (takes into account valence and conduction bands);
• Density of States calculation (for both electron and excitons);
• basic doping capabilities: the choice of the fermi level and binding energy will reflect in the exciton band dispersion;
• other minor improvements.

swcnt-bands-v0.1

Stable enough version of the cnt band structure tool.
For a given carbon nanotube (n,m) parameters, this little script calculates and displays:

• linear and helical unit cells;
• linear and helical Brillouin zones;
• linear and helical electron band structure;
• helical effective mass approximation of the dispersion relation of bright and dark singlet excitons.
